It was conjectured in [Wang, to appear in The Australasian Journal of Combinatorics] that, for each integer k โฅ 2, there exists . This conjecture is also verified for k = 2, 3 in [Wang, to appear; Wang, manuscript]. In this article, we prove this conjecture to be true if n โฅ 3k, i.e., M (k) โค 3k. W

โฆ Synopsis
In this article, we consider the following problem: Given a bipartite graph G and a positive integer k, when does G have a 2-factor with exactly k components? We will prove that if
, then, for any bipartite graph H = (U 1 , U 2 ; F ) with |U 1 | โค n, |U 2 | โค n and โ(H) โค 2, G contains a subgraph isomorphic to H.

The total chromatic number ฯ T (G) of graph G is the least number of colors assigned to V (G) โช E(G) such that no adjacent or incident elements receive the same color. In this article, we give a sufficient condition for a bipartite graph G to have ฯ T (G) = โ(G) + 1.
A formula is developed for the number of congruence classes of 2cell imbeddings of complete bipartite graphs in closed orientable surfaces.
